What brand of device is that Geno?
Chinese copy of a dankung ergonomic dancing/pocket predator ranger loop with a few improvements from amazon. The tubes I made from 1/8 I.D. x 1/16 W. - 1/4 O.D. to Tex-shooter's heavy hybrid specs. The tubes and flat bands that came with it were really way better than I imagined they would be.
